| Anyone know the history? Why two versions? Does it have to something to do with the military trials? |

Quoted:
i know the slides changed from stamped to milled The stamped slide will always have an internal extractor. Some milled slide P220s have an internal extractor. Sig has now switched to the external extractor exclusively as far as I know for the P220. It was the last hold out that had an internal extractor. There are a ton of internal extractor P220s that have been running for decades with no issue. I think the external extractor is just easier to mill than the internal style for the newer slides. I have a milled slide P220 with an internal extractor. No issues as of yet. I think people are reading into it a bit much. Just because Sig moved to the external extractor doesn't mean it is better.. it just might be cheaper. |

My W. German 1993 220 has been flawless since day one with a internal extractor. March 08 I bought a Sig 220 Carry, milled slide with int extractor, and it too has been flawless in about 1300 rounds, including 450 of the Fed HST 230 JHP, 100 230 Gold Dot, and 50 Rem 230 Golden Saber. I do know, just like my int extractor 1911, to keep not only the breach face clean, but all around the extractor. My 220 Carry has a small bevel on the bottom of the extractor, to facilitate the round sliding up and under the extractor hook. Keep that clean too, and you should be fine.
I too think the change to ext extractor was to simplify manufacture and replacement of parts. Yes, some people had problems with their int extractor, but some people have also had problems with their vaunted 1911 with int extractor. |

As stated above. The only thing I will add is that replacement of the extractor is easier if it is an external type. The internal type would require the whole breech block assemby to be removed first, so it's more labor intensive (gunsmithing perspective). The milled slides do not have a breech block to remove.. The milled slide internal extractor slides out the bottom of the slide |
